Ni-Cr: Cr20Ni80,Cr15Ni60, Cr20Ni35, Cr25Ni20 etc.
Nichrome,a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire because it has a high resistivity and resistance to oxidation at high temperatures. 

FeCrAl: 1Cr13AI4, 0Cr19AI2, 0Cr15AI5, 0Cr20AI5, 0Cr25AI5, 0Cr21AI6 Nb,OCr27Al7Mo2
FeCrAl, a family of iron-chromium-aluminum alloys used in a wide range of resistance and high-temperature applications is also used in the form of resistance wires.
